This series is of importance because of the superconducting transition induced in the same parent compound by chemical pressure via P doping. We find that Sb enters the lattice in limited amounts, and does not suppress the SDW transition. A phase separation results when we try to make single crystalline EuFe2 Sb2, limiting the amount of Sb absorbed by the lattice. The Anti-Ferromagnetic transition of the Eu2+ ions is unaffected by this unit cell enlargement. The SDW and bad metal states below and above the high temperature transition show electronic transport analogous to that observed in other series of Pnictides. Intermediate report available at Project at IIT Kanpur (Aug Nov 2009) Under the guidance of Prof Pankaj Jain Cosmic Rays are energetic particles which are incident on the Earths atmosphere from outer space. Finding their direction is important for determining their sources. We use data from simulations (CORSIKA) of showers on the GRAPES array to deduce the direction and opening angle of the conical shower fronts. We aim to determine these from the timing information of the events themselves, and 1

Report available at Project at the Max Planck Institute for the Physics of Complex Systems in Dresden (May - July 2009) Under the guidance of Prof. Roderich Moessner For a Bose-Hubbard dimer, we study quenches of the site energy imbalance, taking a highly asymmetric Hamiltonian to a fully symmetric one. The ramp is carried out over a finite time that interpolates between the instantaneous and adiabatic limits. We provide results for the excess energy of the final state compared to the ground state energy of the final Hamiltonian, as a function of the quench rate. We show the fate of quantum self-trapping when the ramp is not instantaneous. Published in Phys. Rev. B, 81, (2010) Summer Undergraduate Research Fellowship (SURF) at The California Institute of Technology, Pasadena (May - July 2008) Under the guidance of Prof. Re em Sari Binary systems tend to evolve towards the energy minimum defined by synchronous rotation and a circular orbit through tidal interaction between the masses. This evolution can be interrupted if the satellite has a non-zero quadrupole moment - the system can get trapped in a state where the spin and orbital rates are related by integers or half integers. This has been extensively studied in the low eccentricity limit using different models for the tidal interaction. We study this spin-orbit coupling in the limit of highly eccentric orbits. We express the torques in terms of the coefficients of the Fourier expansion of the restoring torque, known otherwise as the spin-orbit H-functions. These H-functions are computed numerically and analytic approximations are developed. This formalism is applied to different models of the tidal interaction. We then use the derived results to study probabilities of capture into spin-orbit resonances. We also briefly look at the implications of the calculations for the spin states of extra-solar planets. Report available at Summer Undergraduate Research Fellowship (SURF) at The California Institute of Technology, Pasadena (May - July 2007) Under the guidance of Prof. Andrew Lange Slabs of birefringent materials, called waveplates, are necessary optical components for CMB polarization experiments. The performance of the wave-plates was studied using a different approach from the conventional jones matrix, which used a 4x4 matrix to represent the transformation of the radiation as it passed through the system. This makes it easier to study the combined effect of the antireflection coatings also. The performance of the waveplate was studied off axis to around 10 o and over two harmonics - at 150 and 225 GHz. The effects of dielectric loss, axis tilt and finite coherence length were also studied. The performances of Crystal Quartz and Sapphire were compared at 225 GHz. The algorithm used enables a complete study of the effect of any parameter on waveplate performance. Report available at Project under the National Initiative on Undergraduate Science, HBCSE (December 2005) Under the guidance of prof Annapurni Subramaniam Performed photometric analysis of open cluster BE - 63 using data from the Hanle Telescope, Ladakh. Determined parameters of the cluster such as distance and age. The project was carried out at the Vainu Bappu Observatory at Kavalur. 2
